ROLLER-SKATE WHEEL.

Specification of Letters I Patent. I Patented June 6, 1916,'

Application filed June 29, 1915. Serial No. 375090.-

`To all whom z't may concern f Be it known that we, FRANK E. BROWN and BURNICE R. BROWN, citizens of the United States, residing at Webster City, in the county of Hamilton and State of Iowa, have invented certain new and useful Improvements in Roller-Skate Wheels, of which the following is a specification.

VThis invention relatesI to skate wheels or casters and contemplates as its principal object the provision of a skate roller formed of twin mating casings, race plates whereby antifriction bearings are maintained in contact with the hub of the wheel.

More specifically, it is an object to provide a pair of annular casings peripherally flanged and having the edges of such flanges stepped for a mutually mating contact, a race plate formed of a single piece being provided for each casing and the casings being equipped with means maintaining them in a braced and spaced relation.

- The above and additional objects which will be hereinafter more specifically treated are accomplished by such means as are illustratedin the accompanying drawings, de-

plates, Fi

.nion, and

scribed in the following specification and then more particularly pointed out in the claims which are appended hereto and. form a part of this application. u

lVith reference to the drawings, wherein there is illustrated the 'preferred embodi- .ment of this invention as it is reduced to practice and throughout the several views of reference designate similar' parts Figure 1 is a-side elevation of the skate caster of this invention,V

Fig. 2 is a plan view of the same subjectmatter, Fig. Bois a vertical sectional view A taken V`on the plane indicated by the lilne 3 3 of Fig. 1, Fig. 4 is anopposite side g elevation of the skate wheel, Fig. 5' is an interior view of one of the -skate casings, Fig. 6 is a detail view of one of the race 7 isa detail of the hub or trunig. 8 is a detail 'of the rivet means spacing and bracing the casings. l l

Each of the casings employed to form the tread of the roller skate caster is the counterpart of the other and may lee-readily pressed or otherwise formed up from a suitable sheet metal which will impart to the wheel the desired lightness and durability.v4

Each casing includes a bodyportion 10 of disk like formation having its periphery supporting twin formed with the inwardly directed flange 11, an annular bead 12 beijng pressed out of the metal at the juncture of the flange 11 with the disk l0. The edge of this annular flange, which forms'half of the tread for the wheel is provided with a series of mortise projections 13 of, equal length 'and spaced to accommodate tions of thel lmating tread casing. These stepped edges of the casing flanges prove a' most effective means of uniting the tread casings while permitting each.casing to be formed`up in the same mannerv` Ball bearing cones or race plates 14 are formed from a single piece of metal in a cup-shaped manner that .provides .an inwardly bent side flange 15 on one edge and an annular lip 16 on the other edge thereof. The body portion disk 10 of each tread casing is apertured to receive a race plate 14 and is formed with directed to surround the aperturwand to Y contact directly with the lip 16 inproviding race plate.

tread casings 10 is formed with an annular` series of apertures'which are alternately of two different sizes denoted respectively at v24 'and 25. The apertures 24 are of the larger size and are each body disk l0 with their centers on the radial center line of each mortise enlargement 13.

The 'smaller apertures 25 on the contrary each have centers placed en the -radial line drawnto the center-ofthe space separating the mortise enlargements and thus alternatelyspa'ce the larger apertures 24'. The

the similar proj ec#y a flangel? inwardlyformed through the l plate is so formed as I purpose of this arrangement is for the" proper reception of the' rivet means'illustrated in Fig. 8 in whichthe shank-or body portion 26 of the rivetis. formed at opposite extremities with a head 27 anda reducedf The diameter of e re dily accomupsetting extremity 28. the shank 26 is such as -tob modated within the larger ap N ures 24' and kthatbgf the reduced extremity 28 is such as to aecomi'nodated readil?7 withinv the e io5 I flange 17 smaller a e'rturesA 25ct the opposite' tread casing, w ich as will be explained, facilitates to a great'degree the assembling of the skate after theparts have been vcut, turned or pressed out from the dies and formers.

The assembler of they roller of this-inven-l tion takes Aa pair of'tread casings 10 and fits Aeach one with its race plate 14, which owing to the construction described is forced 'into a very tight wedging contact with the disk Ball bearings are placed in both of the race plates, which are then brought together on opposite sides of the hub enlargement 22, in such mannerthat the mortise enlargements 13 of the stepped periphf y eries of the casings are `brought into' mating contact with each other, as illustrated to ad- Avantage in Fig. 2.? The rivets 26 may then be inserted through the apertures 24 of either of the casings, and may then have their extremities 28 barred and upset upon the body disk 10l of the opposite casing. In this manner the assembler is not forced to position theJK rivets in a particular place. or through a particular asing but may insert them from either casing at will, producing the wheel caste shown 1n elevation in Figs. 1 and'4.

While in the'- foregoing, however, there has thus been illustrated in the drawings and described in the specification such comv'tenons on said caslngs.

2. A roller including a pair of body members provided with annular inwardly extendingv treads, and interengaging mortises I and tenons on said treads.

.3.. A roller including twin bodycasings,

interiorly directed' flanges providing a central aperture, tread flanges, means mutually interlocking said tread flanges, twin ball plates wedgingly rg'e'ceived withinfthe apertures m provided by the first mentioned anges,an inwardly directed flange on each therethrough, and a hub accommodated in the last said apertures. Y

4. A roller including twin body casings,

interiorly directed ilanges providing a central aperture, tread flanges, means mutually 'interlocking said tread langes, twin ball plates wedgingly received within the apertures, provided by .the -rst mentioned flanges, an annular lip formed on each ball .plate to contact with the first said apertures, an inwardly directed Hangs on each ball plate providing a central aperture therethrough, anda hub accommodated in the last said apertures.

5. A roller including twin body disks -each provided with a central aperture and an annular bead,a" tread ange formed on each bead inte-rengaging mortises and tenons provided on the edge of said flanges, ball plates wedgingly accommodated in said aperturls, a hub, and meansfor connecting said dis S. z k

l6. A rol-ler including tread casings, interengaging means formed on the inner edges of said casings and each casing having an .annula'riseries of apertures'of different sizes and 4alternately spaced, a hub, twin ball plates' clamped between said casings and coacting withsaid hub to form a plurality of ball receways, and rivet means adapted to space and brace said casings and each having diiti'erent sized. ortions for engagen ment with a pair of different sized apertures. v

7. A roller lincluding. a tread member comprising two casings each having flanges co--acting to forxnthe tread, said members ballv plate providing a central aperture being centrally apertured, a hub having' an enlarged portion, bearing members disposed on either side of said enlarged portion and lying within the central apertures of said casings, and means sechring said casings ton gether to assemble said roller.

In testimony whereof we afiixv our signa;

tures in presence of two witnesses.
